Patent EP-0014636-A1 (EP)
Inventor: DELASSUS JEAN
IPC: B22D11/12
Filed: 1980-01-29
Abstract: An electromagnetic inductor for generating a helically moving magnetic field includes a first magnetic circuit having an annular core with radially inwardly projecting teeth and a winding for generating a rotating magnetic field, and a second magnetic circuit formed by foliated bars and a second winding comprising an axial series of circular coils for generating an axially moving field. The two fields combine to generate a field with helical movement. At least some consecutive teeth of the core are hollowed to provide axial grooves in which the foliated bars are disposed. The coils of the second winding are cylindrical and set inside the cylindrical volume defined by the teeth. The inductor is particularly adapted for the electromagnetic rabbling of a billet in a continuous casting process.

Abstract: L'invention concerne une ligne à retard à pas variable pour tube à onde progressive. La ligne est constituée de cellules (10) construites dans des sections (11) du guide d'ondes dans lequel à lieu le propagation de l'onde électromagnétique mise en jeu dans le fonctionnement du tube. Toutes les cellules sont constituées des mêmes éléments, plafonds (1), anneau (3), tige supports d'anneau (4), courst-circuit (2). Le pas variable est obtenu par dilatation ou contraction des cotes à l'intérieur de la section du guide. Une amélioration sensible du rendement du tube est obtenue par l'emploi de lignes faites de trois parties de pas différents, se succedant le long du trajet du faisceau, dont la seconde présente un pas inférieur et la troisème un pas supérieur à celui de la première. Application à la production de hauts niveaux de puissance à grande bande passante, en ondes centimétriques.

Abstract: Magnetic-polymer latex having a concentration of less than 65% by weight of hydrophobic vinyl aromatic polymer particles. The polymer particles have diameters from 0.03 to 5 microns and also have dispersed therein a magnetically-charged material in an amount of from 0.5 to 50% by weight with respect to the polymer portion of the polymer particles. A process for preparing magnetic-polymer latices. Magnetically charged particles are dispersed in an organic phase comprising an organically soluble initiator and an organic monomeric component selected from the group consisting of a single vinyl aromatic monomer and a combination of a single vinyl aromatic monomer and a copolymerizing monomer. The dispersion so obtained is mixed with an aqueous solution containing an emulsifying agent and the mixture is homogenized. Polymerization is then effected to form a magnetic-polymer latex containing hydrophobic vinyl aromatic polymer particle. More organic monomer component may be added immediately prior to or during polymerization. Alternatively, the magnetically-charged material may be dispersed into an organic phase comprising an organically soluble initiator and a water-soluble organic compound. An organic monomeric component is added to the aqueous-organic phase mixture after homogenization and prior to or during polymerization, which is effected to form a magnetic-polymer latex containing hydrophobic polymer particles. The magnetic-polymer latices obtained are useful in paints, magnetic tapes, recordings, and biological applications.
